SAWBUCK.

KSPEGICFICA'IION forming part of Letters Patent No. 628,015, dated July 4, 1899. Application filed November 22, 1898. Serial No. 697,173. (No model.)

To all 'wh/0m, t may concern: Beit known that l, HARRY MrrcHELL,a sub .ject of the Queen of Great Britain, residing at Neepawa, Manitoba, Canada, have invented certain newand usefullmprovementsin Sawbucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and to use the same.

The invention relates to sawbucks, and more particularly to that class which are 'adapted to be folded into compact shape for transportation.

I5 The objects of the invention are to do away with the necessity of putting the knee or the foot upon the stick or log to be held while sawing the same and to provide simple and effective means for holding the stick to lbe 2o operated upon in such manner as to leave the operator in the best position for operating the saw.

It consists in the combination, with the buck, of spring clamping-jaws connected with a foot-lever or treadle and operating through a slotted guide connected with the cross-bar connecting the legs of the sawbuek and in certain details of construction and arrangement of the parts of the sawbuck, as will be hereinafter particularly described and claimed.

In the accompanying drawings, Figure 1 represents a perspective view of the improved sawbuck in operative position. Fig. 2 is a front elevation of the same closed for transportion. Fig. 3 represents a transverse vertical section showing the parts in position for operation. Fig. 4 is an enlarged detail perspective view of the slotted spring-jaw guide-plate; and Fig. 5 is an enlarged detail 4o perspective View of the upper end of one of the legs, showing the saw-holding clip applied thereto. p

1 1 and 2 2 indicate thelegs of the sawbuck, connectedby a cross-bar 3, the construction and arrangement of these parts, except in certain details hereinafter described, being similar to such as are in common use. The outer legs l 1 are perforated to receive the rounded ends of the cross-bar 3, which are 5o firmly secured in said legs, being keyed or otherwise rigidly secured therein. The legs 2 2 are pivoted upon the cross-bar 3 to swing freely thereon inside of the legs 1 1, `which are recessed on their inner faces at 'a and have pivoted to them links or rods 4, which at their opposite ends pass through eyes or staples 5 on the legs 2 and have hooks 4', which engage said eyes for holding the buck in operative position. thelinks slide through the eyes and fold down snugly in the recesses a. Upon the cross-bar 3, at or near the center of its length, is rigidly secured a transverse plate 6, provided with a slot 7, extending across and beyond the bar 3, and within said slot, upon the opposite sides of the bar 3, are arranged the clamping-arms 3 3, formed from a single piece of spring-steel in loop or V shape, preferably brought into close proximity below the bar 3, as indicated at 9, from which point they are bent into the form of a pendent loop or eye lO. The arms above the point 9 diverge thence to their upper ends, which are bent inward toward each other and preferably slightly downward for adapting them to engage the stick being operated upon. The loop portion 10 of the spring is preferably expanded in width or hammered out and made thinner for giving it the desired elasticity and adapting the diverging hook ends of the arms 8 as they are carried downward through the -slot 7 tobe made to approach each other for grasping the stick or log'between them, the angle of divergence of the arms being such as to canse the arms to automatically rise under the tension of the spring for releasing the log when the spring-arms are released for that purpose. The loop or eye 10 has extending through it a suitable strap 0r cord l2, .the ends of which are connected to eyes 13 13 on opposite sides of a foot-lever or treadle 14, which at its lower end is connected by suitable eyes with a cross bar or rod 15, connecting the lower ends of the inner legs 2 2. Also secured i within the loop 10 is `a pendent loop or link 16, adapted when the buck is to be folded for transportation to engage the hook 17, secured to the treadle 14. By this arrangement the In folding the buck treadle is" adapted to swing freely upon the 1 rod 15 under the action or pressure of the operators foot thereon.` The hook 17 is preferably arranged in a depression or cut-off portion in the treadle, as indicated at 18, in such manner that it is brought iiush with or below the surface of the treadle, thereby preventing IOO .lig

its catching the foot of the operator. The legs 1 l are provided intermediate the crossbar 3 and the links 5 with Wedge-shaped tapering blocks 19, which serve when the legs 2 2 are folded Within the legs 1 1 to hold them securely in their folded position. In lieu of the wedges 19 round-headed brass nails or` tacks 19 may be driven into the legs 1 and made to frictionally engage the legs 2 when the sawbuck is folded.

2O indicates an angular clip secured to the righ t-hand leg 2, near its upper end, and adapted to receive and hold the blade of the saw, with the lower or heel end of the saw-frame resting upon the ground when not in use. This clip is rigidly secured to the leg 2, and its inner portion, lying parallel with the inner face of the leg, is suiiciently removed therefrom to receive the saw-blade and hold the same in a vertical position.

By the construction shown and described when a log is placed in position upon the sawbuck the operator places one foot upon the treadle l and pressing down Ward thereon draws the spring clamping-arms S 8 downward through the slotted plate G, thereby forcing the arms inward toward eac-h other and causing them to grasp and through their hooks 1l to firmly hold the log in position during the operation of sawing the same. Upon removing the pressure of the foot from the treadle owing to the outward tension of the arms they are immediately caused to spring upward and outward, thereby releasing the stick or log, which can then be readily removed or moved endwise into position for again operating thereon in the manner described.

In folding the sawbuck for transportation theloop 1G is drawn downward and made to engage with the hook 17 on the treadle, thereby drawing the upper ends of the clampingarms 8 S into the desired close relation to each other, and the links 4 will slide through the eyes 5 and swing down, permitting the legs to be folded, the one pair within the other, in the position indicated in Fig. 2.

In sawing with the buck'described it will be apparent that the legs and back of the operator will bein an upright position and the weight of the body almost directly over the work, which saves the back from strain and the knee and pants from being injured, be-

sides giving to the operator a much feasier and more natural position.

It will be apparent that the form of the treadle or foot-lever and of the other parts of the sawbuck maybe varied from those shown and described without departing from the spirit of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a sawbuck,the combination with the cross-bar thereof, of the oppositely-disposed sliding spring-jaws, the pivoted foot-lever or treadle for operating the same, a suitable connection between said sliding jaws and footlever, and means for forcing said jaws toward each other as they are drawn downward, substantially as described.

2. In a sawbuck, the combination with the cross-bar thereof, of the folding legs, the slot ted plate on said cross-bar, the sliding clamping-arms moving in said slotted plate, and the foot-lever or treadle connected to said clamping-arms for operating them, substantially as described.

3. In a sawbucl, the combination with the folding legs thereof, of the cross-bar, the slotted plate secured to Said crossbar, the spring clamping-arms operating through said slotted plate, and a foot-lever or treadle connected to said clamping-arms for depressing said arms, said arms being adapted to be retracted for releasing the log by their spring tension when the weight on the treadle is removed, substantially as described.

4. lnafoldingsawbuck, the cross-barthereA of provided with a slotted transverse plate, the spring clamping-arms moving within the slots in said plate, 'the foot-lever to which said arms are connected for operating them, provided near its swinging end with a hook, and a link connected to the looped end of the clamping-arms for engaging said hook for holding the springs compressed when the buck is folded for transportation, substantially as described.

In testimony whereof I aix my signature in presence of two witnesses.
